There are two main reasons why renewable energy is better than fossil fuels: renewable energy sources are much more environmentally friendly than fossil fuels, and second only renewable energy can guarantee the security of future energy supply.

Renewable energy sources such as solar, wind and geothermal create negligible environmental damage when compared to fossil fuels such as coal and oil. The burning of fossil fuels creates harmful greenhouse gas emissions that cause global warming and climate change and it also leads to all sorts of environmental pollution. Indirectly, our dependence on fossil fuels also leads to extinction of many species and massive biodiversity loss.

When fossil fuels become depleted, and this is really only a matter of time, world will be forced to look for alternative energy solutions. Since nuclear energy is connected with many safety issues the only logical choice looks to be renewable energy, primarily because of its abundant potential. Our Sun, for instance is the most abundant form of energy available on our planet.

The transition to clean renewable energy sources will no doubt take some time but world has already started making first steps by investing billions of dollars into renewable energy research. The main goal of renewable energy research is to make renewable energy sources more efficient, and most importantly to achieve cost-parity with fossil fuels because fossil fuels still have an edge in costs over many of renewable energy sources.

There is a variety of renewable energy sources and each country can choose a renewable energy source that best suits its needs, whether this is solar energy, wind energy, geothermal energy, biomass, hydroelectric power, etc.

We are too dependent on fossil fuels, meaning that we need renewable energy to improve our energy independence and reduce foreign oil import. More domestically produced renewable energy means that more money stays inside our borders, and more importantly it leads to thousands of new jobs in our country.

The future simply has to belong to renewable energy because this is the best long-term energy solution at our disposal. How long we'll have to wait for this future depends primarily on science. The scientists need to make renewable energy technologies cost-competitive with fossil fuels to start the real renewable energy revolution. Once this happens, even the almighty fossil fuel lobbies won't be able to stop renewable energy from taking over the world.

Hopefully, this future will come sooner rather than later. As president Obama said in 2009 when addressing to U.S. Congress: „To truly transform our economy, protect our security, and save our planet from the ravages of climate change, we need to ultimately make clean, renewable energy the profitable kind of energy.“
